The brief
One open kitchen and dining space, level access to the garden, and somewhere for homework and a sofa.
What DreamSpace did
A single-storey rear extension replacing the conservatory, with two rooflights over the working side of the kitchen and bifold doors to the patio. A structural opening was formed into the existing kitchen wall to make one room.

From first visit to final handover
- 01
Free home consultation
We visit your home, listen to what is not working and talk through what is realistic for the property and your budget.
- 02
Survey and initial ideas
Measurements are taken and early layout options are put on paper so you can see how the space could work.
- 03
Design, permissions and quotation
Drawings are developed, planning and Building Regulations routes are confirmed, and you receive a written scope and quotation.

One named contact, agreed payment stages, documented variations and regular progress updates while the work is under way.
- 05
Completion, handover and guarantee
A joint completion inspection, an agreed snagging list, certificates handed over and your 10-year warranty confirmed in writing.
DreamSpace protections
Six promises, in writing, before we start
You have heard the horror stories. Every one of them starts with something that was never written down. So we write it all down.
Fixed written price
You get an itemised scope and a fixed price before a single tool comes out of the van. If we did not price it, you do not pay for it.
Nothing changes without your signature
Every variation is priced and signed off in writing before the work happens. No end-of-job surprises.
10-year warranty
Your completed work is covered for ten years, confirmed in writing at handover.
FMB member, independently inspected
We are a Federation of Master Builders member — vetted and inspected by someone other than us. You can check the register yourself.
We do not disappear
One named contact from the first visit to the final snag, and we answer the phone after handover too.
Payment in agreed stages
Staged payments tied to work completed, set out in the contract before we start. Deposit terms: [CLIENT DETAILS TO BE ADDED].
Full written terms are issued with every quotation. Ask for them before you commit — to us, or to anyone else.
Questions homeowners ask before getting started
How much does a house extension or conversion cost?
Cost depends on size, structure, ground conditions and specification. Verified cost bands for our own recent Manchester projects are shown on the costs page. Current figures: [CLIENT DETAILS TO BE ADDED]. An accurate figure needs a survey and a written scope.
How long will the work take?
Typical durations for the work we complete: [CLIENT DETAILS TO BE ADDED]. Your quotation states an expected programme, and progress against it is reviewed with you during the build.
Will I need planning permission?
Many single-storey rear extensions, garage conversions and rooflight loft conversions fall under permitted development, but restrictions apply to conservation areas, flats and previously extended homes. We confirm the route for your property before design work is finalised.
Will I need Building Regulations approval?
Yes. Extensions and conversions require Building Regulations approval covering structure, insulation, fire safety, ventilation and escape. We handle the applications and inspections and hand you the completion certificate.
What is included in the quotation?
Your quotation is issued with a written scope of work: preliminaries, structure, roofing, windows and doors, electrics, plumbing, plastering, decoration and the finishes you have chosen. Anything excluded is listed so nothing is assumed.
How do you minimise disruption during the work?
Access routes and floors are protected, dust barriers are used where we open into the existing house, deliveries are planned, and the site is tidied daily. We tell you in advance about noisy or disruptive stages such as steelwork and breaking out.
